Swine fever is one of the most important viral diseases of pigs. It is a systemic disease and is a notifiable disease in most countries. Farmers need to know how to prevent it on their pig farms.<\/em><\/p>\n

1. Causes of swine fever<\/h2>\n

Swine fever is caused by a pestivirus related to bovine viral diarrhea and border disease. There are many strains with different virulence. Its clinical symptoms are very similar to African swine fever and many common diseases, such as salmonellosis; therefore, diagnosis must be made by laboratory testing. Control of the disease consists of culling infected pigs or, as a last resort, vaccination. Like African swine fever, these viruses survive for a long time in frozen carcasses.<\/p>\n

\u2022 The virus is transmitted from infected or carrier pigs in nasal secretions, saliva, urine and faeces. It is highly contagious.<\/p>\n

\u2022 It can enter the herd through contaminated meat (can be transmitted through uncooked pork or processed meat).
\n\u2022 Mechanical transmission is common through boots, clothes, trucks, etc.
\n\u2022 Co-infection with PRR virus<\/p>\n

3. Effective ways to prevent swine fever<\/h2>\n

Swine fever is one of the most important viral diseases of pigs. It is a systemic disease and is a notifiable disease in most countries.<\/p>\n

Producers need to understand how to prevent it for their pig farms through some important notes below:
\n\u2022 Vaccination is effective in areas where the disease is endemic, and in high-risk areas it may be mandatory.
\n\u2022 Most countries without the disease do not include vaccination in their national CSF eradication programs, and it is often prohibited.
\n\u2022 In areas where CSF is endemic, it is common practice to vaccinate all pigs at two weeks of age. Piglets born to vaccinated sows are vaccinated at eight weeks of age. This policy will usually result in eradication of the virus from that area.
\n\u2022 Countries without CSF will prevent foreign contamination, control the import of pigs and pork products, unless they are properly processed, if they come from countries with CSF. In addition, the organic waste that may contain meat products must be heat-sterilized.<\/p>\n

FAQ<\/div>\n
\n
1.<\/span> How dangerous is swine fever to pig herds?<\/div>\n
Swine fever is a highly contagious disease that spreads rapidly, causes high mortality rates, and seriously affects farming productivity if not controlled promptly.<\/div>\n <\/div>\n
\n
2.<\/span> How can farmers effectively prevent swine fever?<\/div>\n
Farmers should strictly apply biosecurity measures, regularly clean and disinfect barns, control feed and breeding sources, and closely monitor herd health.<\/div>\n <\/div>\n
\n
3.<\/span> What should farmers do when pigs show signs of swine fever?<\/div>\n

Farmers should immediately isolate infected pigs, restrict the movement of people and vehicles into the farm area, and contact veterinarians for proper guidance on disease control and management.<\/p><\/div><\/div><\/div><\/div>
